Title: Inverter circuit
Inventor: KINO JIRO
IPC: H02M7/5387
Filed: 1987-09-18
Abstract: PURPOSE:To protect an inverter circuit from overcurrent by interrupting a feedback to a switching element when output current of the inverter circuit are made overcurrent. CONSTITUTION:A current transformer 9 is current-coupled with a main circuit for an inverter, and output currents of the transformer 9 are converted into voltage at a constant ratio by using a CR circuit 13. When overcurrents are flowed through the main circuit and said voltage exceeds a fixed value, a trigger element 7 is turned ON, and a photo-TRIAC coupler 8 is turned ON. Consequent ly, voltage at both ends of a winding 3c for a current transformer 3 is held at voltage (approximately 1V) at the time of the conduction of a light-receiving TRIAC. Accordingly, when the turn ratio of the winding 3c to windings 3a, 3b is brought to 2:1, voltage at both ends of the windings 3a, 3b is held at half (0.5V) voltage at both ends of the winding 3c. Power transistors 2a, 2b are cut off when base emitter voltage is brought to a constant value (approxi mately 0.6V), thus stopping the inverter.

The crucible is heated with the heater 7 to prepare the GaAs melt covered with B2O3 melt. Further, the As container is heated with the heater 11 up to 600-650 deg.C to generate As vapor of 1-2kg/cm<2> vapor pressure. When the GaAs melt is formed, the seed crystal of GaAs on the shaft 12 is brought into contact with the melt and the single crystal is allowed to grow up. At this time, the rotation rate and direction of both the crucible 5 and the shaft 12 are controlled to control the shape of the solid-liquid interface.
